Objective To understand the endemic situation of schistosomiasis in surveillance sites, and to provide scientific reference for schistosomiasis control during the "Thirteenth Five-Year Plan" in Zhejiang province. Methods According to the scheme of Zhejiang provincial schistosomiasis surveillance (revised in 2012), 11 provincial schistosomiasis surveillance sites which represented for water network endemic regions and hilly endemic regions were selected and evaluated. The morbidity of the infection, snail distribution and relevant factors were investigated. The 5 meter-synchronously systematic samplings combined with the environmental samplings were used for snail survey. Indirect hemagglutination assay (IHA) combined with miracidium hatching method were used to evaluate morbidity in humas. Results The residual snails area were 12 100 m² in the 6 surveillance sites from 2012 to 2014. The area with Oncomelania snails,the rate of living snails frame and the mean densities of living snails in 2014 were reduced by 76.22%,53.04% and 73.91% when comparing to those in 2012, and no imported and infective snails were found. There were no local schistosomiasis cases, but 4 advanced schistosomiasis cases and 16 imported schistosomiasis cases were found in the surveillance sites. Conclusion The results of surveillance showed the current stable schistosomiasis endemics and the need of proper control measures in Zhejiang province. There are some residual snail populations and imported schistosomiasis cases in the surveillance sites, thus there is still a risk of re-emergence of schistosomiasis. To achieve the goal of schistosomiasis eradication, we must emphosize comprehensive prevention and control strategy with given priority to the surveillance of residual snails and imported schistosomiasis.
